This skirt is GOTS certified which requires it to contain at least 70-95 % organic fibers. GOTS is the strictest certification for organic material on the market today and include rigid controls of, among other things, chemical use, salaries and working conditions for everyone involved in the entire manufacturing process, from raw material to the final product. Mini Rodini’s GOTS certified products generally contain at least 95 % organic fibers. Since we are working with children’s clothes, the control of chemical use and measures taken for long-term sustainability is of the utmost importance to us.
